The telehandler stability triangle is a core safety principle that every telescopic handler and electric forklift operator must master, which serves as a visual judgment basis for avoiding vehicle tilt and rollover risks in actual daily operation.

The three vertices of the stability triangle are formed by the ground contact point of the two rear wheels and the central point of the front axle of the vehicle, and the enclosed area is the safety range where the combined center of gravity of the whole vehicle and load can stay stably. As long as the combined center of gravity is kept inside this triangle, the vehicle can maintain stable operation under conventional working conditions. Once the center of gravity shifts beyond the boundary of the triangle due to improper operation, the vehicle will lose balance and pose safety hazards.

In actual operation scenarios, many operators tend to ignore the dynamic change of the center of gravity, especially when the telescopic arm is extended to a long outreach distance or the load is lifted to a high position, the center of gravity will move forward and outward significantly, which may easily cross the boundary of the stability triangle. It is recommended that all operators confirm the load weight, ground flatness, extension length of the arm and lifting height before starting work, avoid sudden steering, sudden braking or sudden acceleration when carrying heavy loads, and do not operate the vehicle beyond the rated load range.

For new energy electric forklift and telescopic handler products, the optimized counterweight design of the vehicle body reserves sufficient stability margin for most conventional operation scenarios, but operators still need to judge the safety state in real time according to the stability triangle principle when facing complex working conditions such as sloped ground and long-distance outreach.
